20h1 fixes multi monitor stutter

Multi-monitor setups are very common nowadays, regardless of whether we are talking about work environments or gaming. However, Windows 10 never did manage to handle this setup very well, even if the hardware could support it easily.

For example, Windows 10 users have been plagued by an issue for over a year now which was caused by DWM. This window manager in Windows 10 enables the use of hardware acceleration to render the graphical user interface of Windows.

Having multi-monitor setups caused latency

Users on Reddit commented on the matter, stating that

Most people are running dual monitor setups, and having anything open on your secondary or third monitor will impact frametimes and introduce micro-stutter, sometimes just having a dual monitor will make frametimes/micro-stutter worse even with nothing open on the secondary monitor.

Microsoft fixed the multi-monitor stutter

The fix was first noticed and shared on Reddit by users that are most probably part of the Windows Insiders program.

As you can see in the example below, there is a significant difference in response rate between the unpatched version of Windows 10 and the one that got the fix.

Unfortunately, you’ll have to wait a little bit longer in order to get the fix. This is because it will roll out to Windows 10 users with the Windows 10 20H1 update. Microsoft is expected to roll out Windows 10 20H1 update in March or early April.
